Instead of doing this, wouldn't it make sense to just switch all Tegra
boards to TEXT_BASE=00108000 to match NVIDIA's flashing tool's assumptions?
That way, no board would need to override TEXT_BASE at all.

These assumptions are true for all boards in the standard flashing tool
builds; it's just that non-standard builds exist for some boards (those
that happened to be upstreamed to U-Boot first) that allow use of 00e08000
instead.

Tom, Simon, what are your thoughts here?
